I only pumped the pedal after all the bleeding, did not pump it to the floor, partway maybe 3-4 times when it got hard. I took that to be sucking fluid into the MC after the draining/bleeding/all new fluid. I'll give another try bleeding, maybe fix up a pressure cap and give that a try.

I got the new front brake rotors and calipers/pads on the 84 SD, spent like an hour bleeding the system, putting in new DOT4 fluid. Went around 3 times sucking fluid with the MityVac, was getting a tiny bit of air but it seemed mostly to be leaking around the bleeder threads (I did wrap them

Is it pre-ABS? If so, just open the bleeder valves and let gravity do the work - not going to introduce any air that way (not that I see hoe the mityvac would either). If that doesn't work, and the resevior doesn't get too low, you have a master cylinder to replace/rebuild. On Sun, Jul 14, 2013
